' COMPANY, A CORPORATION OF DELAWARE INSULATING BLANKET AND METHOD OFCONTROLLING THE -DIS'1'OB'1 '.ION THERE)! Application filed June 16,1930. Serial No. 461,618.

My invention relates more particularly to insulating material of thekind commonly known as blanket insulating material and comprisingseparated layers of sheet mate- 6 rial, usually paper, with a body ofinsulating material interposed therebetween and commonly of a characterpossessing such resistance and natural springiness-that it tends to fullout, or fluff, unless restrained, as for 10 example jute, hair or acombination of these materials.

The invention further relates to blanket insulating material which, inits installation forv use, is interposed between spaced supports, suchas the vertical spaced studding of a building wall, and its oppositemarginal edge portions,its vertical edge portions in the case of itsinstallation between vertical studding,bent at substantially rightangles to the intermediate portion of the blanket to fiatwise oppose thesides of the supports, the blankets thus being of substantially channelshape in cross section.

It has been found in practice that the effectiveness of insulatingmaterial of the character above referred to is inversely proportional tothe density of the mass; namely that insulating material of thecharacter stated is more resistant to the transmission of heattherethrough when permitted to become fulled out or flufied bv theexertion of its natural springiness than when in a more densifiedcondition in which the material is more or less compressed, my inventioncontemplating the availing ofthis phenomena in insulation for practicaluse.

One of my objects is to.provide for the augmenting of the insulationproperties of insulating material of the character above stated.

Another object is to accomplish the above stated purpose in aneconomical and simple manner.

Another. object is to provide for the accomplishment of the purposeabove referred to by a construction of blanket which automaticallydeforms, in installing it into operative position, into such a conditionthat the insulating filling is permitted to expand and thereby becomeless dense; and other objects as will be manifest from the followingdescription.

Referring to the accompanying drawings:-

.Figure 1 is a face view ,of a portion of a wall framework shown asequipped with insulation in accordance with my invention.

Figure 2 is a section taken at the line 2 on Fig. 1 and viewed in thedirection of the arrow; and

Figure 3, a cross-sectional view of a modified form of the blanket.

Referring to the insulation-blanket of Figs. 1 and 2, it comprises twolayers 4 and 5 of sheet material such as paper which are spaced apart,with a layer 6 of any suitable insulating material interposedtherebetween and of such character that it possesses in-. herentresiliency or elasticity, as for example, jute, hair or a mixture ofthese materials.

The blanket is produced in flat form and is provided adjacent the linesalong which close to its marginal edge portions along par-.

allel lines as represented at 9 and 10.

In the particular illustrated construction, the insulating blanket isprovided for insulating a wall-structure formed of a series of studding11 spaced apart horizontally in accordance with common practice, theblanket being installed into the spaces between adjacent studding 11.

In the installing of the blanket, in accordance with the illustratedembodiment of the invention, the operator bends back the marginal edgeportions of the blanket substantially along the lines? of stitching tocause these bent-back portions to extend substantially at right anglesto the main portions of the blanket, as represented at 12 and 13, and insuch condition introduces the blanket into the space to be filled asshown in the drawings, the portions 12 and 13 flatwise opposing thesides of the studding 11. The portions 12 and 13 are then secured to thestudding 11 as for example by means of cleats 14 secured, against saidportions, to the studding, as by the nails represented at 15.

In the bending of the marginal edge portions of the blanket to form theangularlydisposed portions 12 and 13, as above stated, the sheet 4becomes distorted in a cross-wise direction, the loose stitching 7operating to permit restricted bodily movement of the sheet 4 inwardlyfrom both edge portions thereof toward the medial line of the blanket,under the force tending to deform this sheet, and thus, by therestraining action produced thereby,'forcing the deformation of thesheet 4 into the buckled condition as rep resented at 16, the stitching9 and 10, which is preferably employed, preventing relative shifting ofthe sheets 4 and 5 at the portions thereof adjacent these linesofstitching.

It will be understood that, if desired, the stitching 9 and 10 may beomitted in which case, if the buckling of the sheet 4 to the extentobtainable automatically by providing the stitching 9 and 10 is desired,the operator will manually shift the sheet 5 to cause its upright edgesto become substantially flush with the corresponding edges of the sheet4 in which position of adjustment of the sheet 5 the cleats 14 .will bedriven into 1 place.

- insulating material forming the layer 6 is thus permitted to full out,or fluff, due to its inherent resistance or springiness therebyrendering it less dense with resultant increase in efliciency inpreventing the transmission of heat therethroughQ If desired the sheetmaterial may be provided to completely enclose or envelop the layer ofinsulating material, such being provided for in the modifiedconstruction of blanket shown in Fig. 3, wherein the enveloping sheet isrepresented at 17 and where formed of a single sheet of paper its freeedges lapped and secured together in any suitable way.

lVhile I have described one method of practicing my invention and haveillustrated and described certain forms of structure in which theinvention may be embodied, I do not wish to be understood as intendingto limit it thereto as my new method may be practiced in other waysandthe invention embodied in other forms of structure Without departingfrom the spirit of my invention.
